国家和地区顶级域现可参与 ICANN 的域名滥用活动报告 (DAAR) 系统


洛杉矶——2019 年 11 月 19 日——互联网名称与数字地址分配机构 (Internet Corporation for Assigned Names and Numbers, ICANN) 于今日宣布国家和地区顶级域 (country code top-level domain, ccTLD) 运营商现可以积极参与域名滥用活动报告 (Domain Abuse Activity Reporting, DAAR) 系统。

ICANN 的 DAAR 系统旨在针对顶级域 (top-level domain, TLD) 注册管理机构面临的域名注册和安全威胁行为进行研究和报告。该数据从一批经过组织的域名系统 (Domain Name System, DNS) 信誉提供商处获取。

如今,ccTLD 运营商也可使用监督系统应用程序编程接口 (Monitoring System Application Programing Interface, MoSAPI) 集合它们的 DAAR 数据。MoSAPI 接口允许注册管理运行机构获取由 ICANN 服务水平协议监督 (Service Level Agreement Monitoring, SLAM) 系统收集的信息。尽管 ccTLD 运营商并不受制于服务水平协议 (SLA) 和 SLAM 监督器,但使用 MoSAPI 将使得所有参与 DAAR 的注册管理机构使用一套统一界面。已经集合的数据将按照每个 TLD 面临的威胁类型(例如:网络钓鱼、僵尸网络命令与控制、恶意软件分布和垃圾邮件)进行明细分类。这些数据集将与通过 MoSAPI 提供的通用顶级域 (gTLD) 的数据集类似。访问这类数据将使得 ccTLD 运营商能与 gTLD 运营商一样,针对每月每种威胁类型的 DAAR 安全威胁水平进行监督。

ICANN 组织现诚邀所有 ccTLD 运营商参与 DAAR 项目,促进全球 DNS 行业更加深入地理解 DNS 滥用行为。如需参与本项目,ccTLD 运营商应发送一份请求至,启动这一流程。

ICANN 的使命在于确保全球互联网的稳定、安全与统一。在互联网上寻找另一个人的信息,您必须在您的电脑或其他设备中键入一个地址——可以是一个名称或是一串数字。这一地址必须是独一无二的,只有这样电脑之间才能互相识别。ICANN 则负责协调这些分布在全球各地的唯一标识符。ICANN 成立于 1998 年,是一家非营利公益型企业,其社群成员遍布全球各地。

Domain Name System
Internationalized Domain Name ,IDN,"IDNs are domain names that include characters used in the local representation of languages that are not written with the twenty-six letters of the basic Latin alphabet ""a-z"". An IDN can contain Latin letters with diacritical marks, as required by many European languages, or may consist of characters from non-Latin scripts such as Arabic or Chinese. Many languages also use other types of digits than the European ""0-9"". The basic Latin alphabet together with the European-Arabic digits are, for the purpose of domain names, termed ""ASCII characters"" (ASCII = American Standard Code for Information Interchange). These are also included in the broader range of ""Unicode characters"" that provides the basis for IDNs. The ""hostname rule"" requires that all domain names of the type under consideration here are stored in the DNS using only the ASCII characters listed above, with the one further addition of the hyphen ""-"". The Unicode form of an IDN therefore requires special encoding before it is entered into the DNS. The following terminology is used when distinguishing between these forms: A domain name consists of a series of ""labels"" (separated by ""dots""). The ASCII form of an IDN label is termed an ""A-label"". All operations defined in the DNS protocol use A-labels exclusively. The Unicode form, which a user expects to be displayed, is termed a ""U-label"". The difference may be illustrated with the Hindi word for ""test"" — परीका — appearing here as a U-label would (in the Devanagari script). A special form of ""ASCII compatible encoding"" (abbreviated ACE) is applied to this to produce the corresponding A-label: xn--11b5bs1di. A domain name that only includes ASCII letters, digits, and hyphens is termed an ""LDH label"". Although the definitions of A-labels and LDH-labels overlap, a name consisting exclusively of LDH labels, such as"""" is not an IDN."
